"The United States currently has one of the lowest corporate tax rates in its history"

Is that fact really that meaningful? As I understand it, the U.S. marginal corporate tax rate is the third highest out of 188 nations. The average of those 188 nations is 22.5%, much lower than the U.S. rate of 38.9%.

When multinational firms make decisions about where to operate, the U.S. tax disadvantage of 16% certainly must be a factor. As I see it, the relative expense of U.S. taxes vs the world should be important. The very slight difference between current U.S. tax rates and historical tax rates - not so much.
